Application filed Ilecember 20, 1916. Serial No. 137,951.

To all whom it may concern? Be it known that we, GlTO STKLHNE and OLor OSKAR KRING, engineers, Sub ects of the Kingof Sweden, and residing at Ludvika, inthe Kingdqm of Sweden, have 1nvented. certain neW"-and' useful Improve-- ments in Methods and Apparatus for Dis- 1 tillation of Liquids,

- This invention has for its object a method of distilling water and other liquids and. an apparatus for carrying out this method.

The purpose of the invention is to arrange the apparatus in such a manner, that the greatest possible part of the heat, which by preference is generated electrically, is utilized for the evaporation of the liquid. Thls will 'be' obtained according to the present invention in such a way, that the vapor,

, generated atthe distillation; is brought to pass from the distilling. vessel'around the same in such a manner, that it by said hot' steam or vapors will be protected from loss ther to utilize the heat of the vapors and to cool same and to cool the condensed prods 'uctsthe heat of these vapors and of the con.-

densed products may be employed to preheat the liquid to be distilled.

In order to illustrate-the invention a ver-- tical section of a distilling apparatus, constructed in accordance with the present invention, is, by way of example, shown on the accompanying drawing in Figure 1.- Fig. 2 is a horizontalsection after the dotted line in Fig. 1.

1 is the distilling vessel, in which the exaporation of'the liquid is efi'ected for instance by means of an electric heating element 2 of suitable construction. To prevent sprinkling the vessel 1 is-prpvided with a cover, at the top provided with one or several openings. The vessel 1 is surrounded bottom of the vessel 4and leads into another ve ssel 7 provided with an intermedial bottom 8 and intended as receptacle for the Specification of Letters Patent.

' 4 liquid to be treated. Thus the vessels 1 and -7 communicate with each other through the Patented SeptQ3, iota;v

pipe fi. The vessel 7 communicates through the pipe 9 with the hopper 10, which 1s provided with an outlet pipe 11 or the like, so

I that the level of the liquid in the vessel 1 will.

be kept constant by continuously supplying' the hopper 10 with a sufiicient quantity of liquid. From the bottom of the vessel 4; a

number of pipes 12 extend downward, passbottom 8 and opening into the chamber 13 below said bottom 8. When the liquid isbrought to boil in the vessel. 1, thevapors cover 3, fill the space between the vessel 1 and the vessel 4 and then pass down through.

the pipes 12, where they are cooled and condensed at first by the cooling. action of the air surrounding the pipes- 12-and thereafter by the cooling action of the liquid in the vessel 7 which at the same time gets heated by the distilling products passing through the pipes 12. The liquid thus preheated in the vessel 7 rises through the pipe 6 into the vessel 1 where it is evaporated. The prodvaried without departing from the spirit of this invention. Thus the condensation of the vapors can be'efiected in another way for instance by aircooling only or by water-. cooling only. Moreover, the apparatus can be provided with devices for separation of I different gases or vapors and so forth.

Having thus described our invention, we declare, that what We claim is:

An apparatus for distilling liquid, comprising, a distilling vessel, means forheating' the liquid in said vessel, a casing surrounding said vessel and spaced therefrom, 7
